Study may Help Explain Cosmic Phenomena in Outer Space

A research team, headed by nuclear physicists at the University of Massachusetts Lowell (UMass Lowell), has made a discovery that might redefine the way atoms are interpreted by researchers and might help to describe the extreme phenomena occurring in outer space.

Physicists Demonstrate Rapid Change of Light Helicity

A collaborative team of accelerator physicists, experimenters, and undulator experts at the BESSY II storage ring has demonstrated a new method to rapidly switch the helicity of circularly polarized synchrotron radiation—up to a million times more rapidly than before.

Quantum-Entangled Light From A Vibrating Membrane

University of Copenhagen. Researchers from the Quantum Optomechanics group at the Niels Bohr Institute, University of Copenhagen, recently entangled two laser beams through bouncing them off the same mechanical resonator, a tensioned membrane. This provides a novel way of entangling disparate electromagnetic fields, from microwave radiation to optical beams. Creating entanglement between optical and microwave fields would be a key step towards solving the challenge of sharing entanglement between two distant quantum computers operating in the microwave regime.

New Method Shows How Bosons Behave Like Fermions

Fermions and bosons are known to behave quite differently under the majority of circumstances. These are two classes in which all particles, ranging from the sub-atomic to atoms themselves, can be organized.

The Mystery of Supermassive Black Hole Formation

Supermassive black holes are billions of times bigger than the Sun, but how is this possible? According to recent observations, these space giants already existed when the Universe was “just” 800 million years old and is currently 14 billion years old.
